FILLED-BAG-SEWING MACHINE.

Applicatipmfiled December 17, 1923. Serial No. 681,263.

The invention relates to new and useful improvements in sewing machines,and more particularly to a. sewing machine for closlng the mouth of afilled bag.

In my prior application, Serial No. 526,116, filed December 31, 1921, Ihave shown a sewing head having stitching mechanism for closing themouth of a filled bag, which sewing head is mounted on a carrier adaptedto travel back and forth on tracks, so that the filled bag while restingon the stationary support, may be closed by the traveling sewing head,the motor for operating the sewing head also being mounted on thecarrier and traveling therewith.

In my application Serial No. 535,334, filed February 9, 1922, I haveshown a filled bag sewing machine similar to that of my earlierapplication, but arranged so that the sewing head passes back and forthover the platform of weighing scales, so that the filled bag may beweighed, and while on the platform of the scales, where it has beenweighed, the mouth thereof may be closed by the traveling sewing head.

The present invention is directed to an improvement in my prior filledbag sewing machine, and has for its principal object to provide anarrangement whereby the sewing head may be positively driven across themouth of the bag while it is being stitched, and whereby the sewing headmay be disconnected from its positive driving mechanism and returned bygravity to its original starting position.

Another object of the invention is to provide means under the control ofthe operator whereby the motor which is mounted on the traveling carrierforthe sewing head may be first connected to the carrier for driving thesame forward to a point where the stitching is to begin, after which, bydepressing the control to a further extent, the stitching mechanism willbe thrown into operation.

A further object of the invention is to provide tracks on which thecarrier for the sewing head and motor travel, which tracks are soarranged that they may be set in horizontal position or in inclinedposition, so that said tracks may be substantially horizontal during thestitching operation and may be quickly placed in inclined position, sothat advantage may be taken of gravity for returning the carrier to itsinitial starting position.

Another object of the invention is to provide a machine of the abovetype wherein the tracks are raised to tilting position by the carrier inits forward movement, and wherein the tilting of the tracksautomatically releases the carrier from its connection with the motor sothat the carrier is free to return to initial starting position.

Still another object of the invention is to provide a machine of theabove type with controlling devices which operate to return the tracksto normal horizontal position through the momentum of the carrier as itreturns to its initial starting position.

These and other objects will in part be obvious and will in part behereinafter more fully disclosed.

The invention is embodied in a machine which includes broadly, spacedsupporting standards which are mounted on suitable rollers or casters sothat they may .be readily moved about from one place in a mill toanother. These standards are spaced a proper distance so as to permitweighing scales to be placed between the same, which are likewisemounted on casters or rollers so that the whole apparatus is readilyportable. These standards are connected by suitable cross barsintermediate their ends so as to form a rigid frame. The standards arealso made in adjustable sections so that the upper portions may beraised and lowered at will by the operator.

Pivotally mounted on one of the standards is a track structure on whicha carrier travels back and forth. This carrier supports the sewing headwhich is so mounted on the carrier as to overhang the platform of theweighing scales so that the bag after it has been weighed may be readilystitched by the traveling sewing head.

A motor is also mounted on the traveling carrier, and is connected tothe sewing head for actuating the same. There is a cross shaft mountedon and traveling with the carrier which is provided with a loose pulleyoperated from the motor shaft, and with a worm wheel also operated bysuitable connections with the motor shaft. This worm wheel is loose onthe shaft. A friction cone member splined to the shaft is adapted toengage the worm wheel Which is continuously moving, and thus connectsthe transverse shaft with the motor shaft. This transverse shaft carriesa driving gear meshing with a rack on the supporting track structure,and causes the carrier to move from one end of the track to the other.There is a second pulley loose on the transverse shaft and operated by abelt from the motor shaft. A second friction cone is loosely mounted onthe shaft and adapted to be brought into engagement with this loosepulley, and this cone clutch member is connected by a suitable belt tothe main shaft of the sewing head.

Clutch controlling members are provided which are constructed andarranged so that when the operator places his-foot on the treadle orcontrolling device for these clutch members, the worm gear will be firstconnected to the transverse shaft and cause said transverse shaft torotate, and thus cause the carrier for the sewing head and motor tobodily move along the tracks. When the sewing head reaches the point tobegin the stitching on the mouth of the bag, a further depression of thetreadle will connect up the belt wheel on the transverse shaft with thesewing head and thus the stitching mechanism will be operated by themotor.

The treadle is connected to a transverse shaft which in turn isconnected to the clutch members in a manner which will be described inde ail for actuating the clutch members to connect up the motor to theparts to be actuated thereby, and which will release the motor fromthese actuated parts when the t-readle is released.

As a means for tilting the tracks, I have provided a means actuated bythe traveling carrier, which raises the tracks to a tilted position,lifting the mot-or, sewing head and carrier as the tracks are tilted.Devices are also provided so as to automatically disconnect the motorfrom the mechanism which causes the carrier to move forward provided theoperator fails to release the treadl'e at the proper time. The carrier,therefore is released from the motor and is free to return, and-thetilting of the tracks causes it to roll down the inclined tracks to itsstarting point. When the carrier reaches its starting point, itautomatically releases the tracks so that the same will be brought backto horizontal position through a the weight of the carrier and the partsmounted thereon.

Referring more in detail to the drawings, my improved machine includes asupporting frame consisting of spaced standards 1 and 2. Each standardis carried by a base member 3 mounted on rollers4-4. Each standard isalso provided with an upper section 5-5 which telescopes in the lowersection of the standard, and the upper section is raised and lowered bymeans of gear wheels 6, one for each standard, meshing with a rack bar 7formed as a part of the upper section of each standard. The standardsare connected by cross bars 8 and 9 which form a rigid frame structure.At the upper end of the standard 1 there is a supporting head 10, whileat the upper end of the standard 2 there is a supporting head 11.

The track structure indicated at 12 in Fig. 2 of the drawings, ispivoted at 13 to the supporting head 10, while the other end of thetrack structure is capable of being raised and lowered toward and fromthe supporting head 11. Mounted on the track structure 12 is a carrier14. A sewing head 15 of the usual construction is mounted on a dependingbracket portion 16 rigidly supported by the carrier 14:. Also mounted onthe carrier 14 is a motor 17.

The frame structure consists of a U bar track member 18 which extendsfrom one end of the machine to the other. Said U- shaped track member 18is rigidly secured to a hinged member 19, and this hinged member 19 issecured by the pivot 13 to the supporting head 10. At the other side ofthe machine there is an inverted T-shaped track member 20 which issecured to a hinged member 21 which is in turn pivoted by means of apivot 22 in a line with the pivot 13 to the supporting head 10. Thesetracks are connected at the opposite end from their pivotal supports toa plate 23. This forms a rigid track structure on which the carrier 14is adapted to travel. Said carrier is provided with two rollers 2-1, 24,which are adapted to run on the inverted T-shaped track member 20. Theserollers are at the rear side of the carrier. At the forward side of thecarrier there is a single supporting roller 25 (see Fig. 7) which runson the lower member of the U-bar track member 18.

It will be understood, of course, that these rollers are carried bysuitable bearings formed on the carrier and operate to support thecarrier so that it can travel back and forth. Mounted within the U-bartrack member 18 is a rack bar 26.

There is a transverse shaft 27 mounted in the carrier and extending fromthe rear side thereof to the front side thereof. Said shaft 27 serves asa supporting means for the roller 25 which is freely mounted thereon andalso carries a gear 28 which is adapted to mesh with the rack bar 26 sothat when the shaft 27 is rotated, the car rier will be positively movedalong the tracks through the engagement of this gear with the rack onthe U-bar track member 18. The roller or wheel 25 is freely mounted onthe shaft 27. The gear wheel 28 meshing with the rack will pull on thecarriage so as to move the shaft 27 bodily and this will cause theroller 25 to roll along the track, turning, of course, in the oppositedirection from that of the gear wheel 28.

This transverse shaft 27 is provided with a worm gear 29 which is freelymounted on the shaft (see Fig. 8). This worm gear meshes with a drivinggear 30 on a shaft 31 carried by a bracket 32. A belt wheel 33 mountedon the shaft 31 is operated by means of a belt 3% from a belt wheel onthe end of the motor shaft 36 of the motor 17.

It will be noted that this motor 1.7 is secured to the upper face of thecarrier by suitable bolts 3T. 37, which rigidly secures the motor to thecarrier. This worm gear 29 is continuously driven while the motor is inoperation. Splined to this shaft 2" is a friction cone 3S. Said frictioncone is capable of moving endwise on the shaft. but any rotationimparted to the cone will in turn be imparted to the shaft 27. The coneis capable of moving endwise compressing a spring 39 so as to makecontact with the cone surface 40 formed on the Worm gear,

and thus it is that when this friction cone 218 is moved into drivingconnection with the gear 39, the shaft 27 will rotate with the gear, andwhen pl'cssurc is released from the cone nit'nibcr Jib, tho spring 39will sepa rate the driving surfaces so that the shaft :27 will cease itsrotations.

This shaft. If is mounted in bearings -ll and 42. one of which iscarried by the sidiwall of the carrier ll. while the other is carried bya bracket arm 43 depending from the upper portion of the carrier.

Mounted loosely on this shaft 27 is a b lt wheel 44' which is connectedby means of a belt 15 to the motor shaft so as to be coir tinuouslyrotated thereby while the motor is in operation. Associated withthisbelt wheel it is a pulley to which is connected by means of a belt17 to the main belt wheel 18 of the sewing head. Said belt 47 runs overidlcrs it). t.) on its way to the sewing head. This pulley has afriction cone ctutch suriacc 50 which is adapted to coop erate with afriction cone clutch surface 51 on the belt wheel 1a. A spring 52normally holds these clutch surfaces separated. When, however, thepulley do is movcd endwisc on the shaft so as to bring the clutchsurfaces into contact. then the motor will, through the pulley to andthe belt 4i" opcrate the sewing head.

The pulley 46 is moved into driving contact with the belt wheel ft bymeans of a lever 53 which carries a. headed screw .11 having a roundedsurface adapted to make contact with the outer rounded surface of thepulley sit and hold these parts in driving connection while they rotate.This lever 53 is pivotally mounted by the depending bracket portion toof the carrier. A shaft 55 extends through the lever and the bracketportion of the carrier and has a splined connection with the lever 53.This shaft 5.1 is mounted in suitable bearings 56 and in" carried by themain track structure. The carrier and the lever 53, therefore, will movealong this shaft. but any oscillation of the shaft will oscillate thelever 53. The clutch member 38 is operated by a lever 8. This lever 58is pivoted at In) to the depending portion 16 of the carrier. Said lever:38 is connected to the lever 53 by a link (it) formed of twotelescoping parts. A spring 61 surrounds the part which moves into itsassociated sleeve and nuts (32 serve as an adjust able abutment for thesyn-lug.

It will readily be seen from the description, that the lever 53; may bemoved so as to move the lever 58 to cause the clutch member 38 to engagethe clutch surface on the worm gear 29, and these parts may be broughtinto engagement before the lever is moved sufficiently far to cause thepulley 16 to clutch up with the belt wheel 44. Thus it is that thecarrier may be caused to move along the tracks before the sewingmechanism is operated. A further movement of the lever 53, which ispermitted by this yielding telescoping link 60, will cause the drivingpulley 17 to clutch up on the belt wheel 14 and drive the same. hen thelever 53 is released. then the springs 52 and 39 will cause these clutchmembers to separate and thus release the carrier, as well as thestitching mechanism from its driving connection with the motor.

The shaft 55 is under the control of the operator through the followingdevices. The shaft. 63 is mounted in suitable bearings 6t, 64 carried byone of the base members 3. This shaft has a foot treadle (35 on itsforward end which is readily accessible to the operator standing infront of the machine. Said shaft (53 also carries an upwardly extendingarm 66 cooperating with arm (37 mounted on a vertical shaft 68. Vhen theshaft 63 is oscillated by depress ing the treadle or releasing thetreadle. this arm 66 will impart to the shaft (38 an oscillation. Theshaft 68 is mounted in bearings (39. 69 carried by the standard 1. Saidshaft extends to a point above the supporting head 10. A bracket 70 iscarried by said supporting head 10. and loosely mountcd in said bracketso as to turn therein is a sleeve 71 carrying an arm 72. The sleeve 71is provided with a rectangular opening' as clearly shown in Fig. 13 ofthe drawings. This rectangular opening is shaped so as to fit the shaft68 which is rectangular in cross section. The purpose of this bracket 70and this supporting sleeve for the arm 72 is to permit the supportinghead 10 to be raised and lowered with the upper section of the standard.and still maintain an operative connection between the arm 72 and thevertical shaft (38 which. of course. does not move up and down when theparts are adjusted. This arm 72 is connected by means of a link 73 to adepending arm 7st which is fixed to the shaft 55.

It will be noted that when the treadle is depressed. the shaft 68 willbe oscillated and this shaft will in turn oscillate the shaft 55. Thusit is that the operator by depressing the treadle. may connect up theclutch members. and when the treadle is released. the springs referredto above will separate the clutch members.

My improved machine is particularly adapted for stitching a filled bagafter it has been weighed. The standards 1 and Q are spaced from eachother and connected near their lower ends only by the cross bars 8 and9. and the cross bar 9 is raised a considerable distance from the lowerend of the standards so that the ordinary weighing scales may be placedin rear of the machine with the platform extending underneath thislowermost cross bar as clearly shown in Figures 4 and 6 of the drawings.

The scales include the usual supporting base 75 mounted on suitablerollers or castcrs 76 so that it may be readily portable from oneportion of the mill to another. and mounted in the base is a suitablesup porting means for the usual platform 77 of the weighing scales.Rising from the supporting base is a column 78 which carries a scalebeam 79. The usual brace 80 is provided. These parts are of the usualconstruction, and do not need further description.

It will be noted that the scale platform is directly beneath the sewinghead (see Fig. 1). and that the sewing machine as it travels along thetrack wit-h the carrier on which it is mounted. will move across theplatform of the weighing scales, and thus it is that the mouth of thebag resting on the scales may be stitched. It is sometimes desirable tostitch smaller sacks, and I have provided an adjustable supportconsisting of a lower member 81 and an upper member 82 which telescopeson to the lower member 81. The lower member is provided with a series ofopenings 83 in which the pin. of a bracket 81 can be inserted. There aretwo brackets. one at each side. and these serve to support the uppermember By adjusting the pin brackets from one hole to another. thesupport may be varied in height so as to suit the size of bag which isdesired to be stitched.

As has already been described, the track structure is pivoted on thepivot bolts 13 and and is adapted to be raised to tilted position onthese supporting pivot-s. The supporting head 11 is provided withlaterally projecting arms 85. These arms are each provided with a stopscrew 86 which threads through a sleeve 87 mounted at the outer ends ofthe arms 85. A set nut 88 may be used for locking the screws in theiradjusted positions. The plate 23 which connects the two tracks on whichthe rollers of the carrier run. is adapted to engage these stop screwsand rest thereon. The weight of the carrier. of course. tends to depressthe right-hand end of the track structure as viewed in Fig. and thisbrings the plate into contact with these stop screws. There is a bracketmember 89 secured to the upper face of this plate on which the U bar 18is secured (see Fig. 1). The track 20 is secured to the plate direct.

As a means for raising the free end of the track structure, 1 hawcprovided a swinging bracket 90 on which are mounted rollers 91. 91.adapted to engage the under face of this plate 23. This bracket 90 isprovided with perforated arms 92. 92, which are journaled on pins 93.These pins 93 are each carried by a bracket 94 and are held in thebracket by a set screw 95.

A control rod 96 is secured to the bracket 90 by means of a pivot pin 97which passes through ears carried by the bracket, and the end of the rod96 is located between these cars. \Vhen the rod is pushed to the left asviewed in Fig. 11, it will bring the bracket arms 92 to an uprightposition (see Fig. 11), and this of course, will raise the rollers 91and lift the free end of the track structure. An arm 98 is rigidlysecured to the supporting head 11 and is provided with a stop screw 99which limits any further movement of these bracket arms 92. The free endof the track is now raised and the tracks are inclined. This rod whichoperates to raise the free end of the tracks is provided with a stopcollar 100 which in turn is provided with a buffer 101. This rod 96extends through a rib 102 forming a part of the depending bracketportion 16 of the can rier. \Vhen the carrier moves to the left asviewed in Fig. 4, this rib 102 will strike the collar 100 and move therod 96 to the left, thus raising the tracks. The carrier is driven by amotor and therefore, it is the movement of the carrier actuated bv themotor which lifts the free ends of the tracks to inclined position. Theoperator watching the machine, is supposed to release the treadle whenthe ends of the tracks come up and thus release the carrier from themotor so that the carrier is free to run down the inclined tracks to itsnormal starting position. If, however, the operator does not release thetreadle, the carrier will still be released from the motor by reason ofan automatic control consisting of an arm 103 fixed to the control shaft55, and a rod 104 carried at the outer end of said arm and dependingtherefrom, and passing through an opening in a bracket piece 105 whichis rigidly connected to the supporting head 11. A out 106 on the lowerend of this rod may be moved to different set positions, and it will benoted that when the track raises, the rod 104 will move up through thebracket piece 105 until the nut 106 engages the lower face thereof,after which the rod can move no further and this will move down on thearm 103 and turn the shaft so as to release the clutches.

'hen the clutches are released, then the carrier runs down the inclinedtrack to normal starting position. There is another control collar 107on the rod 96 provided with a similar buffer 101. The rib 102 on thecarrier striking this sleeve 107 will swing the bracket arm 92 so as tomove the rollers to the position shown in full lines in Fig. 11, andthis will allow the free end of the track to drgip through the weight ofthe parts sup porte thereby.

It will be understood, of course, that the sewing head and the carriermove from left to right as viewed in Fig. 2. The bag is placed on theweighing platform of the scales and weighed. After it has been weighedand is ready to be stitched, the operator depressing the treadle willclutch up the worm gear 29 with the motor and this will drive thecarrier forward. The sewing mechanism, however, is not yet operated andit is not desired to operate the same until the sewing head reaches thepoint where the stitching should begin. When this point is reached, thenthe operator by depressing the treadle to a further extent, will coupleup the pulley 46 with the motor, and this will operate the stitchingmechanism.

It will be noted that I have, in a sense, a dual drive actuated througha single control by the operator, which, when depressed to a certainextent operates the carrier, and to a further extent, operates thesewing mechanism. The operator keeps the treadle depressed, and thecarrier moves along the tracks while the bag is being stitched. The stopcollar 100 is so set that when the stitching of the bag is completed,the carrier will engage this stop collar and will push the rod endwise.and through the brackets 92 will raise the track to inclined position.At the same time, if the operator has not released the trcadle, thecontrol shaft 55 will be forcibly turned by means of the depending rod104 so as to release both clutches. This not only stops the stitchingmechanism, but disconnects the carrier from the motor so that thecarrier is free to run down the inclined track, which it does, until itengages the stop collar 107.

The momentum of the carrier as it runs down the inclined tracks willmove this stop collar and the rod to which it is attached to the left,as viewed in Fig. 2. Through this operation, the tracks are released sothat the weight of the parts carried thereby will lower the same tohorizontal position ready for the moving of the machine forward againfor stitching another bag.

When the tracks return to this lowered position, they are received firstby cushioned springs 108 mounted in sleeves 109 carried by the arms 85of the supporting head 11. These cushion springs allow the track togradually settle on to the stop screws 86 and prevents any sudden jarwhich might injure the parts. The strength of the cushion springs can bevaried by means of abutments 110 which are threaded into the sleeves 109and are held in adjusted positions by nuts 111.

\Vhile I have referred to the tracks as being in horizontal position,when the carrier moves forward for stitching the bag, it will beunderstood that the stop screws 86 on which the track structure restscan be lowered so that when the carrier loaves forward,

the tracks will be sli htly inclined downwardly and this will aid in theeasy moving of the carrier forward.

It will be apparent from the above det-cription that I have provided afilled bag :ewing machine wherein the sewing head travels in astilretantiallv strz ight horizontal line during the --i itching ol thebag, after which it brought to a position where it travels in aninclined line moving downwardly toward its starting position, so thatthe vele o movement for the stitching head is forward in a horizontalplane. thence upwardl and tinall v I'tttiWYtll'tllf f along a lineinclined to the horizontal to its original starting point.

It will be noted that the rack bar 26 which is engaged by the gea' 28which propels the carrier back and torth lr; secured to the upper flangeot the U-har ttmning the track. The v-ieight of the carrier at the frontside thereof is carried by the roller 25. These machines are intendedtor stitching tilled bags, and are used in mills where there is muchdust in the air, and it is a great advantage to have the, rack har upside down so as to lteep the du t and dirt from collecting hetween theteeth of the 'aclt bar. In other words. by the arrangement shown in thedrawings. the rack har is kept clear of obstructing material so that the-arrier travels back and l'erth ver easily.

It is ohvionse that minor changes in the details of con ruction and thearrangement of the parts ma he made without. departing l'rom the spiritol' the invention as set l'orth in the appended claims.

Having thus described the invention. what I claim as new and desire tosecure by Let ters-Patent. is
